Water Line Repair in Longmont: Main Line Leaks and Burst Pipes

The main water line runs underground from the curb stop or meter to the point where it enters your house, usually through the basement wall or up into a crawlspace. When it leaks, you may lose pressure throughout the home or notice a wet patch in the yard long before you see water indoors.

Signs of a Main Water Line Problem

• Grass over the line route that stays greener or squishier than the rest of the yard
• Low pressure at every faucet, not just one
• The meter moving while nothing inside is running
• Dampness on the foundation around the pipe sleeve in the basement
• Rusty or discolored water from an older service line
• Sudden loss of water after a hard freeze

Frozen and Burst Pipes

Northern Colorado winters bring nights well below freezing, and pipes along exterior walls, in crawlspaces, garages and unheated basements are the ones that freeze first. Ice expands inside the pipe and splits it, and the leak only shows up when it thaws. We thaw frozen lines safely, replace split sections and suggest insulation or rerouting so the same spot doesn't freeze again.

Repair or Replace?

• Section repair: one damaged spot on an otherwise healthy line is cut out and replaced.
• Full replacement: older galvanized or worn copper service lines with repeated leaks or poor pressure are usually best replaced end to end.
• Trenchless options: on suitable lots we burst or pull the replacement pipe between two small pits, leaving driveways and mature trees alone.

Before Any Digging

We have buried utilities marked through 811 before excavating, and we coordinate with the City of Longmont when work involves the meter or curb stop. Responsibility for the service line can differ between the city and the homeowner depending on where the leak is, so we tell you what we find. Pinhole leaks inside the house as well? Our repiping service covers the interior lines.
